GMDSS stands for which of the following?

• A. Global Maritime Distress and Safety System
• B. Global Marine Distress and Safety Service
• C. Global Maritime Data and Safety System
• D. General Maritime Distress and Safety Scheme

Answer: (A)

GMDSS stands for Global Maritime Distress and Safety System, an international framework that coordinates distress signaling and safety communications at sea. It isn’t a single device or a service; it’s an integrated system bringing together multiple communication technologies and procedures worldwide so that a vessel in distress can quickly raise an alarm and responders can coordinate a timely rescue. The use of “System” signals this integrated approach, spanning satellite and terrestrial links, digital selective calling, NAVTEX, and other safety networks. The other phrasing options don’t fit the official naming or scope—they substitute terms like Marine, Service, Scheme, or Data, which don’t reflect the global, coordinated safety framework established for maritime distress communications.
